Description

A kind of BGA for printed board clamping tears down and reconstruct mounted welder
Technical field
The utility model is related to a kind of BGA for printed board clamping and tears down and reconstruct mounted welder, is BGA device on carrying out printed board Part is disassembled and is changed frock clamp used during artificial tin scraping cream before weldering.
Background technology
For printed board assembly shop, when printed board BGA device needs manual tearing down and reconstructing due to reasons such as damages, due to BGA device encapsulation and pad specificity, generally require manual manufacture BGA change weldering tool it is operated by artificial tin scraping cream technique Afterwards, then with BGA reclamation work platform carry out the welding of BGA.In the technological operation manually scraping tin cream, need to keep printing plate level Fixing, BGA changes weldering tool and tightly fits with printing plate face, and operating personnel need to exert oneself downwards in BGA pad locations when scraping tin cream Scrape tin cream, and then it is suitable to ensure that tin cream deposits accurate, the mutual adhesion in position when being attached on pad, storage.At present, plant operations people Member carries out changing welder when making to printed board BGA device, and the printed board due to reprocessing all does not have technique edges, and clamping is difficult.Operator Member directly printed board is placed on workbench and carries out scraping tin cream operation by other people are hand steered, and this mode makes printed board no Method keeps level and consolidates, and easily slides, and then largely effect on the precision scraping tin cream and quality and cause while making power BGA device weld failure.Existing printed board clamping tooling exist its clamped height too high it has not been convenient to make power downwards, and workman behaviour Make downwards power easily cause printed board and excessively bend and then destroy printed board or the situation of pad.So being badly in need of a kind of convenient clamping Various sizes printed board, its clamped height is only above operating desk seldom, and can ensure that there is support in the middle part of printed board, will not make print Making sheet is bent downwardly excessive frock to improve the quality of printed board BGA device welding and to ensure its welding efficiency.
Content of the invention
The purpose of this utility model is to overcome in prior art, printed board clip position too high it has not been convenient to regular to Under make the operation of power, no support in the middle part of printed board and easily cause the drawbacks such as printed board flexural deformation, provide and a kind of be used for printed board The BGA of clamping tears down and reconstruct mounted welder, can be highly relatively low with fast clamp sizes printed board, frock, and middle part can support print The frock clamp of making sheet.
The utility model for achieving the above object, be employed technical scheme comprise that:A kind of BGA for printed board clamping tears open Change mounted welder it is characterised in that:Including chassis, deflector apron, fixing end block, end of stroke, fixing end guide rail, slide and lead Rail, clamping device I, screw rod frame, hand are twisted screw rod, clamping device II, are printed plate supporting device;
Described undersurface of bottom disc is rectangular-shaped, is in rectangular channel, on two sides before and after bottom surface respectively in the middle of rectangular bottom surface It is provided with a baffle plate, in the corresponding inner face both sides of two baffle plates, be respectively symmetrically fixes a fixing end block, an end gear Block, fixes a deflector apron, every side shield and deflector apron before the fixing end block of both sides and end of stroke respectively Between respectively constitute a gathering sill;
Described fixing end guide rail is fixed on above two fixing end blocks, and two clamping devices I are separately positioned on fixation On the guide rail of end, two clamping devices I guide perforate I by the strip that the guide pad I being each provided with is provided with fixing end guide rail Cooperation, make two clamping devices I horizontally moveable on fixing end guide rail, the adjustable interval between two clamping devices I;
The fixing guide pad II in described rail plate two ends is correspondingly arranged in two gathering sills, II point of two clamping devices It is not arranged on rail plate, the strip that two clamping devices II are provided with rail plate by the guide pad III being each provided with The cooperation of guiding perforate II, makes two clamping devices II horizontally moveable on rail plate, between two clamping devices II Adjustable interval;
Standing screw frame on the end face of rail plate, is provided with hand on screw rod frame and twists screw rod, adjustment hand twists screw rod, sliding Dynamic guide rail is horizontally moveable on two baffle plates;
Two described plate supporting devices of printing are arranged in the rectangular channel on chassis.
The beneficial effects of the utility model are:The utility model has that Stability Analysis of Structures, chucking power be big, structure member is simple simultaneously Single, easy to process, cost is relatively low, simple to operate, have two kinds of method of clamping, possess highly relatively low level consolidate clamping various The printed board function of size, in the operation that operating personnel firmly scrape tin cream vertically downward, can guarantee that there is support in the middle part of printed board, Make printed board will not flexural deformation, and make power convenient it is adaptable to the special suitable environment of plate face, hommization are printed in pressing energetically Design is strong.The utility model Special-purpose printed board BGA device changes scrapes tin cream operation during weldering, with strong points, facilitates durable, parts More simplify, processing cost is low, beneficial to batch production.The utility model improves workshop in printed board BGA device rework process The operating efficiency of middle BGA components and parts welding it is ensured that BGA device reprocess progress.The utility model tears down and reconstruct weldering in printed board BGA Can be used widely in field.
